As many of you know more than most drafts are big busts even if you have a top 5 selection. You can easily spend $260k-$520k just on draft points in one season
In the past I'd agree with you completely. But the new changes that let you see actual skill levels as well as 19 year olds getting Strong instead of Respectable skills, means it's a bit more viable.
For my last draft, I had a bit of a gamble (that failed). Great trainee, height was around what I wanted, but only 4 ball potential. I believe that's supposed to be a 50/50 shot between Perennial All-Star and Superstar. He was the former. If he was actually a Superstar, he'd be a perfect pick. The next version of my team needs trainees with specific skill/height combos. So this weeds out all of the guys who don't fit the criteria. After that it's just hoping they're Superstar minimum.
So if you're just looking for generic high potential youngsters, I don't advise spending points on draft picks. If you're doing something funky with your training and builds, then it's more likely to be worth it.
